Symmetry, Crystal Systems and Bravais Lattices

There are seven different kinds of lattice systems, and each kind of lattice system has four different kinds of centerings (primitive, base-centered, body-centered, face-centered). However, not all of the combinations are unique; some of the combinations are equivalent while other combinations are not possible due to symmetry reasons. This reduces the number of unique lattices to the 14 Bravais lattices. WebApr 12, 2024 · This Learning & School item is sold by 3DCentral. Ships from Richmond, VA.
